In the medical sector, enterprises in the Shenzhen region utilize TPU films to manufacture medical catheters and IV bags, with their biocompatibility certified under ISO 10993. Automotive applications include sealing strips (exhibiting a compression set of less than 30%) and injection-molded interior components. Protective cases for electronic devices employ polyester-based TPU with a hardness ranging from 90A to 95A, featuring a controlled surface friction coefficient within the 0.4–0.6 range. Shenzhen-based companies also leverage bio-based TPU materials to produce highly transparent, abrasion- and scratch-resistant mobile phone cases that comply with international environmental standards while integrating magnetic charging and NFC modules.
Emerging application areas include:
Smart Wearables: Developing adaptive protective gear by harnessing the shape-memory properties of TPU.
Eco-friendly Packaging: Utilizing recyclable TPU films as a substitute for PVC in food-contact materials.
Sports Equipment: Producing 3D-printed TPU midsoles for athletic footwear with an energy return rate exceeding 65%.
